It is a common design on others, and has been seen on in flight failures. There is an interesting video of a King Air 350 with symmetrical failure of both wings at outboard attachment points. While it neatly fit into the swimming pool at impact, it didn't end well. Whether the wing has a single, 2, 3 or 5 joins in the spar is dependent on the designers balance of requirements at the start.
